Stephen Colbert’s latest SuperPAC ad: Vote for Herman Cain (VIDEO)

Since he discovered that South Carolinians can’t write his name in on the ballot during Saturday’s GOP primary, Stephen Colbert,…er, the super PAC that is supporting him… has pivoted to a new strategy: Ask voters to write in the name of Herman Cain. The Cain Train is back on the rails! (And Herman will be selling books, he has assured supporters in an e-mail. Sheeh!)

And a new ad released Wednesday night — narrated by Samuel L. Jackson — urges voters NOT to vote for Colbert “who is turning our election into a circus.” Yes, a pro-Colbert Super PAC is paying for an ad opposing Colbert and in support of a candidate who is on the ballot but no longer running.
